Cortana and Siri battle it out in Microsoft's latest ad

Microsoft and Apple have a long history of taking shots at each other (remember I'm a Mac?), and Microsoft's latest TV spot continues that proud tradition.

The commercial features Siri on an iPhone 5S and Cortana on a low-end Lumia 635, where Microsoft’s voice assistant handles requests involving people and locations - all tasks Siri is unable to process.

Cortana is available on all Windows Phone 8.1 devices, but is currently only officially available in the US. To access Cortana in Singapore, you'll have to set your region settings to US and language settings to English (US).
